That reminds me ... I'm using a 1200 fusible link in my Mustang 5.0 !! The short was the infamous ignition switch (subject of a Ford Recall). Nearly burned the car down! It didn't break the fuse link but it bubbled it. The link failed two years later. I used the 1200 link cause I had one handy. I know the 1200 one will work better (I mean it will blow out if necessary) because ...

The fusible link burnt out in my 1200 a couple of times, which is why I had carried a spare ... On the 1200, I never did have a real short. I think it burned because of oxidation on the link itself. The big spade terminals seemed to get corroded for some reason.

But even so, an electrician should look for a short ... doh!
